CHUCK AND TOOL HDLDER.

Specification of Letters Patent. Patented J r1620, 1922.

Application filed September 16, 1920. Serial No. 410,659.

To all whom it may concern Be it known that I, TIMOTHY C. FOLEY, acitizen of the United- States, residing at Renovo, in the county ofClinton and State of Pennsylvania, have invented a new and useful Chuckand Tool Holder, of which the following is a specification.

This invention refers. to chucks and tool holders for planing purposesand is designed for use in connection with planers of a size capable ofoperating upon a large number of units at one time.

While not confined to any particular type of work the invention isespecially adapted for planing interior and exterior horizontal andvertical portions of shoes, wedges and the like .used in locomotivepedestals and in other situations, where rapidity and accuracy of thework is desirable, the construction being such that numerous pieces ofwork may be fastened to the planer table and finished without changingthe position of the work,

These desirable qualities are brought about by the invention byproviding a chuck capable of holding numerous pieces of work intandemand by providing a tool holder capable of carrying tools operatingat one timeupon' various portions of the-work.

The invention will be best understood from a consideration of. thefollowing detailed description taken in .c'onnection with theaccompanying drawings forming part of this specification, with theunderstanding, however, that the invention is not confined to any strictconformity with the showing in the drawings, but may be changed andmodified so long as such changes and modifications mark no' materialdeparture from the salient features of the invention as expressed in theappended claims.

In thedrawings:

Fig. 1 is a side elevation, with some parts in section and other partsbroken away, of a chuck arranged to carry numerous pieces of work which,in the figure, are shown as locomotive pedestal shoes.

Fig. 2 is an end view of the planer bedshowing two-chucks in place withrows of shoes clamped therein and the tool holders in position to actupon those surfaces of the shoes to be planed.

Fig. 3 is a plan view of the structure shown in Fig. 2 but omitting thetool holders.

Fig. 4 is a longitudinalsection of one of the camp heads of the chuck.

.Fig, 5 is a section on Fig.

Fig. 6 is a vertical section of an; adjustable support for the work. i

F ig. 7 is an elevation of a multiple I showing the adaptabilitythereof.

Figs. 8, 9 and 10 are various views of ferent types of work. Referringto the drawings there isshown undercut or inverted T slots 2, both thetable and its slots following the usual practice and hence needing noparticular description. Adapted to the table is a suitable numberof aplaner table 1 provided with longitudinal blocks 3 constituting supportsfor shoes such as are used 'on locomotives and .termed pedestal shoes,but which may be'replaced in the planer by wedges or pieces'of miscel;

laneous work asneedful or desirable. j

diate stem or post of a suitable widthiand height and provided with abase oexte'nding on opposite sides of the post 4 and furnished with anintermediate longitudinal rib 6 adapted to fit snugly yet freely in oneof the Each block 3 is formed with an intermeslots 2. The base 5 isfurnished near each end with a bolt hole 7 to be traversedby a bolt 8,the head 9 of which is square andis located in :the undercut portion ofthe slot 2,

and aunt 10 is applied to the other end of h the bolt above thecorresponding portion of the base 5. may be securely fastened at anypoint along any one of the grooves 2. Extending through the post 4 inadirection lengthwiseof the base 5 is a hole or passage 11, and when asuitable number of blocks 3 is assembled upon the planer the passages 11are in alines ment and are traversed by a rod 12 long In this manner,the blocksj3 I enough to extend at each end beyondfthe post 4 of theterminal blocks. Each end of the rod' 12 is screw threaded, as shown at13, and a nut 14 is applied thereto, while a spacer sleeve or sleeves 15may be applied to one end of the rod 12 for take-up putposes, thecorresponding nut 14 whereadjacent to" the sleeve 15 having a washer16in terposed.

The base 5' is wider than the. post4' and 1 .there are recesses 17 onopposite slides of the. post 4. In the upright planeof thefreg cesses 17and extending crosswise of length of the block 3 is afdovetailfgroo'veor seat 18 in which'is fittedyadovetail tongue 19 of a jaw-20 havingtoothederserrated' side faces 21 slightly expanding as "they from thetop of the post 4. The upper of the post et on opposite sides of the jaw20 has sunken portions 22 leaving terminal rest surfaces upon which workmay be supported, this being particularly valuable where the surface ofthe work engaging the post is rough. Adapted to opposite sides of eachpost at is an upright work engaging jaw 2-ltoothed or serrated on theupright face designed to engage work, the toothed face being indicatedat. The jaws 2e. when formed separately from the post 4, have taper pins26 fitting taper sockets 27 in the body of the post. lVhen desirable thejaws 24 may be made in one piece with the posts 4. in which case thetaper pins 26 are omitted. The jaws 241: are prevented from turning byhaving their lower ends 28 fitting in the recesses 17.

Tapped into the base on opposite sides of and spaced to the trout andrear of the post l are screw bushings 29, each interiorly threaded forthe reception. of an adjusting screw provided at the upper end with asquare or other suitably shaped head 31 prtwidcd with a swiveltermination 32 adapted to receive and support the work at a suitableheight with respect to the teeth 25 of the jaws 24.

In order to secure on the planer table the work to be planed which workmay consist of locomotive pedestal shoes 33 as shown in Figs. 1, 2 and8, the bolt or rod 1 is loosened by unscrewing either or both of thenuts 1%, and the blocks 3 are distributed along the rod with the bolts 8loose, but still tight enough, to prevent the blocks from being ortcriall g" disturbed. 'lhe pedestal. shoes 33 are then assembled hetween the jaws 20,'with end portions Si and 35 of the pedestal shoesengaging or closely approaching the serrated or roughened faces 21. Nowby tighteningup the nuts ll, or one of them,. the blocks 3 are allcaused to approach lllllil the shoes are tightly clamped between thejaws 22. after which the bolts 8 may be finally tightened to hold theblocks 3 in place without dependence upon bolt or rod 12.

For some work the screws 30 are relied. upon and the Cl ends are raisedhigh enough to cause the work to be engaged by the jaws 24 along theirserrated or rough ened faces 25.

The jaws 20 and 24 provide means for clamping a great variety ofarticles to hold them in position for; treatment by planer tools.

' In order to treat a row or gang of articles representing thewvork midpositioned and clamped in alinement onthe planer table, thercis provideda combination tool holder 36. shown in l? This tool holder has a saddleportion 37 terminating in depend ing arms 38, provided with tool heads89 Let-20,025

of the shoes may be simultaneously acted upon by the planer. and as thelatter is capable of treating quite a large number of pedestal shoes atone time the entire work The general shape of pedestal shoes and wedgesvaries for certain classes of loco motives. ln' Fig. 8, there is shown aplan view, a side view and an end View, of a pedestal shoe 33* ofchannel form with the shoe of the same height throughout instead ofhaving one end cut off as in the case of the pedestal shoe 33. In Fig.9. there is shown a wedge block 33 in plan, side elevation and end view.the wedge block 33" being a plain wedge. In Fig. 10. there is shown asimilar'wedge block 33 in plan, side elevation and end view, except thatthe wedge block is of channel form.

In Fig. 7, the chuck is shown supporting a series or gang of blocksbeing planed and held in the chuck in different positions, illustratingthe adaptability of the chuck for operating upon different articles atone time. In the case of wedges, the' post 4 is provided with a notch,or recess 43, permitting the inclination of the wedge so that the tooltil will plane the inclined face of the wedge.
